Wow, some set-up! Very nice indeed.
I decided to go for the big Tobh. Built my very first dual coil (32 Kanthal, five wraps) an hour ago, and am at this moment happily vaping on Southern Steam's Remember the Alamo. It's running at 1.4 ohms on my MVP2 - big contrast to the PV's above! - and clearly not using the Tobh's full potential, but giving me a better vape than I'm used to, and shows the big beast is versatile.
Out of the box though, I found it very difficult to get the sleeve off the deck, and now that it's on again, it won't shift to adjust airflow. I'm not looking forward to changing the wicks! Not sure if this shows Tobeco's wonderfully close machining, or the newness of the O rings.
(For any fellow noobs - the build on the Tobh was indeed a lot easier than on the 22mm Igo-W7. Everything bigger so easier to see, and post-holes on the negative posts far easier to work with, than tying wire around screws and keeping them there while tightening down.)
